From being a small child I have only EVER used rectangle! Thats all I ever use with the children!
We had this debate with uni once... if you notice... only the word rectangle is used in any 'official' documents we recieve from government/ofsted/other 'big bods'. We were advised to stick with rectangle because of this!
Also.... I wish the world would make its mind up and stick to one thing!! How confusing is it for a child who is learning shape names to be told rectanlge by one person and oblong by another??
I think its REALLY important as a setting to discuss this and make a decision as to which you will use and then stick to it!!
Personally for me.... its rectangle every time! :soapbox::blush::rotfl: :sorry:
